CULTIVATOR.

Application filed February 7, 1927. Serial No. 166,444.

view taken on the line 2 2 of Fig. 1; the I 4 the like, whereby the hands of the operator are both free for driving.

A further object of the invention is the rovision of a cultivator wherein the plow earns are hin 'edl connected at their forward ends to t e. rame to permit both vertical and lateral swinging movement thereof and are yieldingly and adjustably supported adjacent their rear ends. A further object of the invention is the provision of a cultivator having improved adjustable means for limiting the movement of the rear ends of the plow beams toward each other, and also with means for supporting the plow beams up out-of operative position, as when driving from one field to an- I other.

A still further object of the invention is the provision of a riding cultivator so designed that the under portion of the apparatus is clear except for the plow beams and yielding support therefor, whereby the drivers view 4 of the ground and of the cotton or the like being cultivated is unobscured.

With these and other objects in view, as will appear as the description proceeds, the invention consists of. the novel features of construction, combinations of elements and arrangements ofparts as hereafter fully described and pointed out in the claims.

A full and complete understanding of the invention may be obtained from a consideration of the accompanying drawings forming a part of. the disclosure; it being understood that while the drawings show a practical I form of the invention, the latter isnot confined to the showing thereof, but may be changed and'modified so long as such changes.

and modifications mark no material departure from the salient features-of the invention as hereinafter fully described and claimed. I

In these drawings Figure 1 is a view in top plan of a cultivator involving the features of this invention;

Figure 2 is a longitudinal, vertical, section trating the manner in which the front ends of the plow beams are supported from the frame; and

Figure 5 is a fragmentary detail view illustrating a portion of the; cultivator with. a different form of implement carried by the plow arms. I

In the embodiment of the invention illustrated in the accompanying drawings, the numeral 1 designates a frame of the cultivator, which is supported upon the shaft 2 upon opposite ends'of which are mounted wheels 3. As shown, the shaft 2 comprises two axle portions 4 carrying the wheels andan offset cen tral portion 5 passing over side members 6 of the frame. The frame 1 preferably is substantially rectangular in form and supports a drivers seat 7 centrally at the rear thereof.

varying distances from the frame 1 and from I the ground. As shown, these means com rise a pair of vertical members 15 depending rom portion 13 of the frame so as to be movable towards and from each other thereon. member 15 preferably comprises a pair of angle elements 16riveted together in spaced relation torconstitute in efiecta sin le ele- "ment having a central longitudinal s 0t. A

U-bolt 17 passing around the frame portion 13 serves to hold each element 16 fast to the frame while permitting,.upon loosening 05 the nuts 18, the sliding of the upper en the member 15 on the frame. A series of apertures 19 are provided in each member 15 to selectively receive a coupling pin 20, preferably of wood to constitute a break pin, which hinge e ement 22 carried by the forward end Each I asses through an aperture 21 in a of the plow beam 14, the other element 23 of the bin e being made fast in the usual manner to t e plow beams.

fl ll In order that the plow beams, particularly a the rear ends'thereo may be yie dingly supported at any desired height, compression springs 26 are disposed between a stationary part of the frame and the plow beams. As'

shown, a U-shaped angle bar 27 extends upwardly from and is fast to the side members 6 of t e frame and slidably supports a pair of hook. members 28 the horizontal portions of which eng e selectively under pairs of pins 29 carried y the top portion of the bars 30. The bars 30 extend through the compression springs 26 and the enlarged lower ends thereof enga e the lower ends of the sprin s.

The enlarge ends 32 of rods 33 engage t e u r ends of the springs 26 and the lower en s of the rods 33 attach to eye-bolts 34 fast at an intermediate point to the plow beams 14.

It willbe observed that, by.reason of this construction, the rear ends of the plow beams .14 may be yieldingly supported in a plurality of positions and that should one of the plows 35 engage a tree-stump, or alike obstacle, and the rear end of the plowbeam be raised thereby, the rod 30 will easily become disengaged from the hook members 28 and the pin 20 will, when the strain is sufficient,.break and wholly release the plow beam from the frame and thereby prevent injury to the apparatus.

While it is desirable'for the operator to be able to control movement of the plows entirely with his feet, it is helpful, in some kinds of work, to limit the inward movement of the plows toward each other. For this purpose, spreader elements 36 are provided and comprise L-shaped arms securable in adjustable positions adjacent one end of the plow beams 14 as by U-bolts 37 selectively positionable in any pair of apertures 38 so that the vertical portions 39 of the spreader elements engage each other and limit the inward movement of the plow beams. It will be observed that the spreader elements do not interfere with the independent action of the plow beams except to. limit their inward movement, that is, movement toward each other, and these elements may be removed or loosened and turned into alinement with the beams when not needed.

The usual ieces 40 are provided on the rear ends of e plow beams for engagement,

by the footof the operator and, referably and as shown, foot rests 41 depen from the frame 1 in such position that the plow beams 14 may be raised and rested thereon, as for instance when the apparatus is out of operation for, sa driving from one field to another.

Pre erably and as shown, a curved plow foot 42 is pivotally attached to each plow beam 14, as by a bolt or rivet 43, and may be made fast in adjusted positions by means of a second bolt 44 passing throu h the beam and, selectively, through one of t e pairs of apertures 45 in the enlarged bifurcated end 46 of the plow foot.

From the foregoing, it will be observed that there has been provided a cultivator wherein the action of each plow beam is entirely controllable by one foot of the operator, the plow beams may be yieldingly mounted in any desired position with respect to each other; the

apparatus is so arranged that 'no portion thereof obscures the drivers view in the operation thereof, and the plow beams are independently'adjustable in all directions to cause them to function properly for varying I des of work and for various different orms of plows, sweeps and the like'which may be em loyed therewith.

VVhatIc aim is:

1. A cultivator including a wheeled frame, a pair of plow beam supporting-members depending from the frame, a pair of plow beams pivotally connected to the respective memers by a releasable connection, and means on the frame yieldingly and releasably supporting the plowbeams whereby, upon engagement of a low carried by one of the beams with an o stacle, the releasable connection and the yielding support will be released and the beam be thereby entirely freed of the plow frame.

2. A cultivator comfirising a frame, a shaft including apair of a e portions and an offset portion fast'to and overlying side portions ends of the plow beams from the frame.

3. A cultivator comprising a wheeled frame, a pair of beam supporting members depending from the front portion .of the frame, plow beams having pivotal and hinged connection at their forward ends to the respective members to permit m'tivement of the beams in both vertical and horizontal planes, means for yieldingly supporting the mamas rear ends of the plow beams from the frame, and means depending from opposite sides of the frame which serve both as foot rests and beams having pivotal connection attheir 'for- 10 Ward ends to the respective supports, and

spring means for supportin the rear ends of the beams yieldingly in adwsted positions, said means including a connection intermediate the beams and frame which remains fixed 1 under ordinary operating conditions but readily becomes disconnected when undue strain is brought to bear upon the beams.
